Grooving Kingston is probably due to the fact that most tracks from 1970-1972 originate and many were produced by Lee Perry and the best of the 3 box sets of JAD, shooting the entire contain of Bob Marley and the Wailers between 1967 to 1972. the other box sets are Man to Man and Fy-Ah, Fy-Ah. with all 3 is official releases of Universal Music and not any bootlegs !!!
